SEEGIFIGATION forming part of Letters Patent N0. 689,958, dated December 31, 1901.

Application filed March 16,1901. Serial No. 51,439. (No model.)

nois, have invented a certain new and useful Improvement in Heaters, (Case No. 1,) of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

Myinvention relates to heaters, and has for its object the provision of an improved form of heater that will furnish a moist heat.

The heater of my invention is a hot-air heater wherein the air is heated, preferably, by a number of burners, the heat from the burners being conveyed through suitable flues. A plurality of lines is preferably employed for the burners, one for each flue, a water-chamber surrounding the upper portions of these fines, while the burners are preferably located in the lower parts thereof. The water-chamber is common to all of the lines, so that, in effect, asingle body of water is subjected to the heating action of a given number of separate gas-flames. By this arrangement the water is vaporized not only through the agency of the heat as it passes through the flame-fines, but is also heated by the hot gas and air that by means of my construction may find access to the upper surface of the water. The vapor may pass through vapor-fines that are preferably located in line with the flame-fines and which communicate therewith, the upper ends of the vapor-fines being open to the extraneous atmosphere. In order that the vapor and the heat may be properly directed into the room in a manner to prevent the irregular distribution thereof, I provide a cap that serves to bring about an intermingling of the vapors, &c., from the various fiues before they are passed into the outer air.

The heater of my invention is particularly well adapted for use where gas-heaters are employed, although the invention is not to be limited to this particular service.

I will explain my invention more fully by reference to the accompanying drawings, in which Figure 1 is a perspective View of a heater constructed in accordance with my invention,

and Fig. 2 is a cross-sectional view on line 2 2 of Fig. 1.

Like parts are indicated by similar characters of reference in the views.

The base aof the burner may be of any suitable form to give the required stability to the structure. A suitable means for conveying fuel extends longitudinally of the heater, which means is preferably in the form of a gas pipe I), from which a number of gasjets a project. The flow of gas to the pipe '1) may be controlled in any suitable way, as by means of a main cock d. The base of the burner supports a series of flame-fines 6, each of which preferably contains a single gas-jet 0. These flame-fines are preferably open at both extremities and are inclosed by a ledge f, upon which the water-chamber g and the vapor-fines h, carried by the water-chamber, may be removably secured to light the gas-- jets. Other means may also be employed for lighting the gas-jets. The water-chamber g is preferably common to allof the gas or flame flues and also to the vapor-fines, free access being had between both sets of fines and the water-chamber. The lines 6 and h are preferably placed in alinement. The heat serves to vaporize the water not only through the com munication of heat from the flame through the walls of the lines 6, but also by contact of the heated air with the upper surface of the water, so that the requisite moisture may be imparted to the heated air as it passes into the room. The water may from time to time be replenished through the spout 2'. The vapor and heated air passing through the vaporflues h h are momentarily assembled Within the space afforded by the cap Z, which is provided for this purpose. In order that the space 70 may have communication with all of the fines h, the cap Z is mounted upon supports m, that serve to maintain the cap a proper distance above the vapor-lines without impairing this communication.

By providing a plurality of flame-fines and a plurality of vapor and hot-air fines not only is the desired vaporization of water socured in a most effective manner, but I increase the radiating-snrface afforded by the large exposed outer surfaces of the fines. By this arrangement a very effective heating apparatus may be produced which is devoid of the many objections that are usually urged against heaters of this type.

Iprefer the particular relative arrangement of the various parts of the heater herein set forth; but I do not wish to be limited to the precise details of construction shown, as it is obvious that modifications may readily be made without departing from the spirit of my invention.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent- 1. In a heater, the combination with means for producing a plurality of flames, of a plurality of flame-fines for separating the flames, a water-chamber surrounding the fiame-flues and common to same, the fines projecting through the bottom of the water-chamber, whereby a space is afforded between the water-chamber and the flues for the reception of water, the said flame-fines being open at their upper ends, whereby the water may be heated by the flames through the material of the flues and by contact of the heated air with the upper surface of the water, vapor-fines open at their ends and having communication with the water-chamber at their lower ends, and a cap Z affording a space R within which the heated vapor, &c., from the flues of the heater may be gathered and then forced into the outer air, substantially as described.

2. In a heater, the combination with means for producing a plurality of flames, of a plurality of flame-fines for separating the flames, a water-chamber surrounding the flame-flues and common to the same, the flues projecting through the bottom of the water-chamber, whereby a space is aiforded between the water-chamber and the flues for the reception of water, the said flame-flues being open at their upper ends whereby the water may be heated by the flames through the material of the flues and by contact of the heated air with the upper surface of the water, and vaporflues also in communication with the waterchamber and having communication with the outer air, substantially as described.

In witness whereof I hereunto subscribe my name this 27th day of February, A. D. 1901.
